I am a first Generation guy, so I have a question for the 2nd Gen guys. I had the opportunity today and executed on the opportunity to purchase a 1973 Type LT camaro. Its loaded to the gills, with AC, PS, PB, loaded gauge package and everything works, etc, etc. It has these strange portal type windows in the rear seating area (top of Rear Quarter panel). It has been babied and garaged its whole life. Purchased new in 1973 in NoCal and moved to Colorado in 1981. All records including the original purchase order were included. it has 54K original miles on it. Overall great condition with no rust. I now own it, but don't know if its valuable or if its something i can modify. Can anyone tell me about the Type LT camaros? I am trying to get educated on this car. I rarely leave anything stock, so don't want to accidentally ruin something that might be rare and valuable.
